摘　　要：项目需要实现软件系统的在线升级,软件系统比较复杂,升级脚本程序需要做多种操作才能完成升级。要求软件系统在升级成功后,具有恢复到前一版本的能力;当升级失败时,能恢复到升级前的状态。通过分析软件系统的组成、配置,借鉴数据库系统中的事务系统原理,设计了一个升级脚本程序模型,并按此模型实现了升级脚本程序,满足了项目需求。A project requires updating its software system online. To update a complicated software system, the program of update script needs to do lots of work. The program of update script must have an ability to restore the software system to previous version after updating it successfully, and it can also restore the software system to the latest status if the update is failed. After analyzing the component and the structure of the software system, referring to the theory of transaction used in database system, a model of update program is designed, and the program of update script is implemented too. The program of update script satisfies the need of the project.
